Re: federal Mag. primers 1 thousands biger than CCI
Interesting to note that. I've only used CCI and now Winchester primers in my Lee Progressive press. Lee's instructions warns you to not use Federal primers in their presses. Now I know why.

Quote:
1) Are the primer pockets swaged since it is military brass? 2) What load are you using? 3) WHY magnum primers in such a small case? Magnum primers raises pressures in a small case. This can lead to problems. I have never had a problem with Federal primers in GI 5.56mm brass as long as the primer pocket is properly swaged!
